How can absolute paths prevent errors in PHP includes on Linux systems?

Using absolute paths in PHP includes on Linux systems can prevent errors by ensuring that the correct file is always included regardless of the current working directory. This is especially important when including files from different directories or when the script is run from different locations. Absolute paths provide a fixed reference to the file location, eliminating any ambiguity and reducing the chances of including the wrong file.

<?php
include '/var/www/html/includes/header.php';
?>
